baby still wont hold bottle?

My baby will be 9 months on the 3rd...he still won't hold his bottle...he lays back with both arms outstretched and opens his mouth and waits. Its funny but at the same time frustrating lol. He wont hold a sippy either. We even tried putty sippy wings on his bottle. Please tell me there are others out there that have LO's that still wont hold their bottles? Is this normal or should i be concerned?

my munchkin will hold her bottle but she will not sit back to drink it. She tries to drink out of it like a straw so we get nothing but air the she gets a tummy ache not sure how to help her with that she does not like being helped.
